Video Add
LMVAdd.DLL - ILMVAdd, ILMVAddDisp
ILMVAdd.h
The add filter can be used for enhancing night vision or dropping more light on dark sources to clarify objects. The effect is performed in 2 ways, the first yields a frame rate divided by the number of added frames, while the other almost preserves the frame rate by using previous frames to output each sample. The output is of course not the same from the two methods. The filters functionality is exposed through both user and programming interfaces.
Video Auto Contrast
LMVAutoCont.dll - ILMVAutoCont
ILMVAutoCont.h
The Auto Contrast filter performs color leveling at the luminance (grayscale) level, introducing no color cast. It makes the dark values darker and the light values lighter, which automatically enhances shadows and brightens the video stream. It also maximizes the tonal range of the image and enhances the contrast and intensity using the image's histogram and a color distribution-based algorithm.
Video Auto Intensity
LMVAutoInt.dll - ILMVAutoInt
ILMVAutoInt.h
The Auto Intensity filter performs color leveling on the RGB channel
(the sum of the R, G, and B channels), introducing no color cast.
It makes the dark values darker and the light values lighter, which automatically
enhances shadows and brightens the video stream. It also maximizes the
tonal range of the image and enhances the contrast and intensity using
the image's histogram and a color distribution-based algorithm.
Video Auto Level
LMVAutoLvl.dll - ILMVAutoLvl
ILMVAutoLvl.h
The Auto Level filter performs color leveling on the individual R, G
and B channels, treating each of the R, G and B channels as a separate
entity, introducing no color cast.
It makes the dark values darker and the light values lighter, which automatically
enhances shadows and brightens the video stream. It also maximizes the
tonal range of the image and enhances the contrast and intensity using
the image's histogram and a color distribution-based algorithm.
